  • excellent rocks, better customer servcice
Size: 10 Pounds Color: Manten
Ordered 10lbs of manten stone under the impression I would receive multiple rocks, but received only. Granted, it was a large rock, but I was a bit disappointed. Graciously, the seller sent me some extra rocks free of charge and they are very nice tasteful pieces. 10/10 would buy again.

  • Worth it
Size: 10 Pounds Color: Elephant Skin
I got 10lbs of the elephant skin stones for my 5 gallon Fluval tank that houses my veil betta (first time doing a planted tank). Great size pieces and I used all 10lbs as I wanted the tank to have a lot of texture. The only thing is the rocks were a bit “dull” orange-y/ grey in color and not as “white” as they appear in the stock photo. But I still like them and would recommend them. ... show more

  • Not what I ordered
I purchased the Red River rock as I thought it would look nice with my bearded dragons enclosure and provide a nice flat spot for her to bask. Instead I received a bunch of smaller, rounder black rocks. Will be returning.

  • Gray Slate Stone
The quality of the gray slate to build aquarium decorations is excellent! I used Loctite clear silicone to assemble a gray slate wall! Highly recommend!

  • NOT NATURAL - PAINTED CONCRETE
Size: 5 Pounds Color: Gobi Desert
The media could not be loaded. I ordered the Gobi Natural Rock for my aquarium. I “looked” real when it was dry, like my other rock in my other aquarium, but when I added water, it’s clear that it is PAINTED. I looked closer at a dry piece, and it is painted concrete. Total scam.

  • Exactly has described
Size: 5 Pounds Color: Black River
Added these to my freshwater tank and they look like they Naturally belong there! The shape allowed me to arrange them in a way that I liked, and they really were a great addition for the money!

  • Size and amount not as advertised.
If you want more than 4 rocks, don't buy these. (see photo - scissors for scale) They arrived on time and in good shape, and they are black lava rocks; however, they are not the variety of either quantity or sizes advertised, which is why I'm leaving 2 stars. As seen in my photo, I received 3 huge rocks and one medium-small, for a whopping 4 total rocks. In the advertised photo from seller it shows about 15 small to medium rocks. I could break them apart, but that creates sharp edges, which is extra work to file down and changes the shape of the rocks. I was hoping to finish this project before my classes start in a week, so I don't have time for that. I have to change my whole concept now, and luckily I'm creative and can make something different work, but I don't appreciate the misleading photos from the seller. I could've avoided this hangup if the details were more representative of the amount of rocks provided. The local stores here only sell red lava rocks, so I'm SOL and of course not willing to buy again from this seller. That's for sure. ... show more
